JS console error on Group Boards page

Loading group boards page causes console error from Vue. Nothing breaks (as the component isn't used anyway)

TypeError: Cannot read property 'hasAttribute' of null
from (boards_bundle.js:295)

Cause

this line:

  canAdminList: this.$options.el.hasAttribute('data-can-admin-list')

if the element .js-add-issues-btn does not exist. We should either check for this.$options.el, or check for that element before rendering the component
